Recently approved by FDA:

A transdermal patch containing 8% capsaicin (NGX-4010, Qutenza) showed tolerable safety in long-term use for post-herpetic neuralgia and HIV-related neuropathy, researchers said here.

The patch also seemed safe and effective in a short-term study in painful diabetic neuropathy, according to research presented at the American Academy of Pain Medicine meeting.

The 8% capsaicin patch was applied for 60 to 90 minutes in the open-label studies reported here, following a preparatory application of lidocaine cream or other topical anesthetic. A single treatment was used in the 12-week diabetic neuropathy study.

Just under half of patients had at least a 30% reduction from baseline in pain scores, and one-third had a reduction of at least 50%.

Maximal pain reductions in most patients were achieved over a two-week period after patch application, and were maintained through week 10, with a slight uptick seen in mean scores at week 12.

Evaluations at the second and sixth weeks after treatment showed 48% and 47% of patients, respectively, reporting "much" or "very much" improvement.

This looks promising for PN and I asked my pharmacist to get the product, so I could try it...

In the meantime, late this afternoon I have tried applying 5% Lidocaine cream one top of one foot and Topricin cream to the other: both products are working well enough, so far, making the pain bearable for now...

This morning I took 2 Curamin tablets, a product that claims a synergistic multiplication of Curcumin benefits by a factor of 20: it worked well enough for my PN foot pain for about 3 hours...

As usual, the testimonials are glowing and fall barely short of reviving week old corpses...
